• •A Macroscopic Fundamental Diagram for a general network with one-to-many OD demands is analyzed.•A new inverse problem of dynamic user equilibrium with a periodic boundary condition is presented.•An analytical formula for the network throughput is derived by solving the inverse problem.•A sensitivity analysis reveals conditions of decreasing in the network throughput.•A distributed signal control for improving network performance is presented based on the sensitivity analysis. This study aims to analyze the relationship between a macroscopic fundamental diagram (MFD), which relates vehicle accumulation with throughput at the network level, and the spatial distribution of congestion (congestion pattern) in a general network with one-to-many origin-destination demands. In particular, we clarify the causes of a decreasing branch of MFDs and the influence of local signal controls on the (global) network throughput. For this aim, we present a new inverse problem of the dynamic user equilibrium assignment by using a periodic boundary condition, and an analytical formula of the network throughput for a fixed accumulation is derived by solving it. This enables us to incorporate the effects of network configurations and route choice behaviors into the analysis of the network throughput. By conducting a sensitivity analysis of this formula, we identify the types of congestion patterns that cause the decrease in the network throughput and examine a network signal control for improving network performance.
